pennae ef176dcf7e nixos/*: automatically convert option descriptions
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running

    nix-doc-munge nixos/**/*.nix
    nix-doc-munge --import nixos/**/*.nix

the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.

`ZSH_AUTOSUGGEST_STRATEGY` is an array that specifies how suggestions should be generated.
The strategies in the array are tried successively until a suggestion is found.
There are currently three built-in strategies to choose from:
- `history`: Chooses the most recent match from history.
- `completion`: Chooses a suggestion based on what tab-completion would suggest. (requires `zpty` module)
- `match_prev_cmd`: Like `history`, but chooses the most recent match whose preceding history item matches
the most recently executed command. Note that this strategy won't work as expected with ZSH options that
don't preserve the history order such as `HIST_IGNORE_ALL_DUPS` or `HIST_EXPIRE_DUPS_FIRST`.
